PIE-PLATE ATTACHMENT.

Application filed February 24, 1928. Serial No.1256,560.

This invention relates to pie plate attachments of the tvpe shown in my Patent #1,640,409, in which a detachable ring is provided which is adapted to be set. in position on the plate rim, so that the pie crust may be built up against it, and will be retained in the built up position thereby until after the pie has been baked, after which the ring may be removed.

l/Vhile the construction of my said prior patent will serve the purpose for wh ch it is intended, it has several objectionable features which it is the purpose of the present in: vcntion to overcome,the more important of which are the high cost of manufacture, the difiiculty of cleaning after use and the 11ability'of distortion from use.

The object of the present invention therefore is to provide a device of the above described type which may be manufacturedat greatly reduced expense, as compared with prior devices for the purpose, wh ch may be readily cleaned after use and whlch. will be sufficiently rigid to prevent distortion from ordinary use. 0

For a more complete disclosure of my 1nvention, reference is made to the following specification, in connection with the accompanying drawings, in which:

Fig. 1 is a plan view of a preferred embodiment of my invention.

Figs. 2, 4 and 5 are detail sectional vlews at the lines 22, 44, and 5-5 respectively of Fig. 1 and l Fig. 3 is a detail side view of a sectlon of the attachment.

According to my present invention provide a strip of thin sheet metal of sultable width, which is adapted to be molded transversely by being passed between die rolls, similar to the ordinary crimping rolls in general use. Said strip is shaped to provide a heavily fluted edge portion a. the flutes in which taper to an intermediate, or base portion 6, which is located approximately in the plane of the ring, and a depending edge flange 0, or cylindrical portion, which extends from the base portion oppositely with relation to the fluted portion and approximately per pendicularly to the base portion, but preferably so that the internal angle between the base and flange is slightly obtuse, or so that the latter flares slightly with relation thereto. The formation of the fluted portion a is such that each external concavity tapers in depth from the edge of the fluted portion to the base, so that what may be considered as the middle portion of the bottom of each external concavityextends obliquely inward from the base portion, the depth thereof thus increasing from a maximum at the edge to nothing at the base. The middle of the bottom of each internal concavity extends ap proximately perpendicularly to the base, the maximum depth of the internal concavities also being at the edge: and tapering down to nothing at the base.

In constructing the attachments, strips of metal are passed between moulding rolls so that they are shaped transversely in the form above described. The molded strips are then cut into suitable lengths and each section thus formed is bent into circular form and its end portions are overlapped to an extent to produce a ring of the desired internal diameter, so that the inner surface of the overlapping portion fits against the corresponding portions of the outer surface of the overlapped portion, as shown in Fig. 5, said portions being secured together at two points by rivets, as d, or by an other suitable means, as solder. The lappe portions, as thus secured will effectively resist lateral distortion by reason of their intimate engagement at diflerent angles. Also the an ularly disposed base and flange portions e ectively act to stifien the ring and hold it in circular form.

' The manner of using the device is identical with that disclosed in my said prior patent and is indicated in Fig. 2, as it will be placed on the rim of a plate, as 6, so that the base portion 6 rests on the top side thereof and the flange 0 encloses its edge, after which the dough may be built up against the fluted portion.

After the baking operation, be readily lifted upward, and faces above the base 6 incline inward from the base, except the middle line of the internal flutes, which may be approximatel perpendicular, as shown. The crust usual y shrinks slightly in baking so that ready removal is permitted.

The above described construction may be produced at. small expense, as the forming operation, by passin between molding rolls, may be rapidly performed, while the subsequent step of cutting the strip into suitable lengths, apping the ends and connecting them, may be easily performed, so the total cost of production'will be lessthan half of that of my prior constructions.

the ring may as all the sur- I claim:

1. A pie plate attachment comprising a ring composed of a continuous strip of sheet metal bent into circular form and having its ends joined, said ring having one edge portion of slightly greater internal diameter than the diameter of the edge of the plate rim, to permit the same to be removably fitted thereon from the top side, and an in termediate portion, adapted to engage the top side of the rim to support the ring on the plate, the opposite edge portion of said ring being fluted and the flutes thereof being tapered in depth from the edge to said intermediate portion.

2. A pie plate attachment comprising a ring composed of a continuous strip of sheet metal having its ends joined, said ring having one edge portion cylindrically shaped and of slightly greater internal diameter than the diameter of the edge of the plate rim, to permit the same to be removably fitted thereon, and an inwardly extending intermediate portion adapted to rest on the top side of the rim,

the opposite edge-portion ot the ring being fluted and the flutes thereof being tapered in depth as they extend from the edge to the inner portion of said intermediate portion.

3. A pie plate attachment comprising a ring composed of a continuous strip of sheet metal having its ends joined, said ring having one edge portion cylindrically shaped and of slightly greater internal diameter than the diameter of the edge of the plate rim, to permit the same to be removably fitted thereon, and an inwardly extending intermediate portion adapted to rest on the top side of the rim, the opposite edge-portions of the ring being fluted and the bottoms of the external cavities thereof being inclined inward from said intermediate portion and said cavities increasing in depth from said intermediate portion to the edge.

In testimony whereof, I have signed my name to this specification.

WILLIAM HOUSTON.
